BRAINTREE (CBS) – Police in Braintree are stepping up patrols and looking for a man who may have tried to abduct a 13-year-old boy.

The boy told officers he had just stepped off his school bus at the intersection of Liberty Street and Wildwood Avenue on Tuesday around 2:30 p.m., when a man in a dark green van started following him.

According to police, the driver rolled down the passenger side window down and told the boy to “get in the car.”

When the boy refused, the man pulled ahead of the boy, drove the van up on a curb to cut him off, opened the passenger door and grabbed the boy’s wrist. The boy was able to escape and run home.

The suspect is described as a white man with short red hair, sideburns and stubble, thirty to forty years old and wearing jeans and a dark blue polo shirt.

Police say the van may have tinted or darkened out back windows and that the van may be a Toyota Sienna.

According to Braintree Dept. Police Chief Russell Jenkins, officers are increasing patrols around elementary and middle schools and detectives will be patrolling in unmarked vehicles.

Police do not believe there is any connection between the incident and an incident last week in Whitman.
